.Application` led June 27, 1922. Serial No. 571,221.

(FILED 'UNDER THE ACT 0F MARCH 3, 1883, 22 STAT. Il., 625.)

To all 'whom t may concern:

Be it known that I, WILLIAM A. BORDEN, major, Ordance Department, United States Army, a citizen of the United States, stationed at Washington, District of Columbia,

have invented an Improvement in a Stabilizer or Fin Assembly of a Bomb, of which the following is a specification.

The invention described herein may be used by the Government, or any of its officers or employees in prosecution of work for the Government, or by any otherperson in the United States, without payment to me of any royalty thereon, in accordance with the act of March 3, 1883.

In the construction of the stabilizer or iin assembly of a bomb it is desirable that the parts be so designed as to lend themselves to quantity production; that the fins or stabilizers be so held that there is small chance for distortion thereof and that the base cap may be readily and easily assembled on the bomb body.

The present invention has been devised 95 with a view to accomplishing the foregoing desirable results.

With these and other objects in view, my invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment herein disclosed ma be made within the scope of what is clalmed without departing from the spirit of the invention Practical embodiments of the invention are illustrated inthe accompanying drawings, wherein Fig. 1 is a view in side elevation of a fragment of a bomb with a iin assembly constructed in .accordance with the invention in place thereon, parts being in section;

Fig. 2 is a rear elevation of 4the same, parts in section; A

Fig. 3 is a view in side elevation, partly in section, of a modified form of the device; Fig. 4 is a section on the li'ne 4.-4 of Fig. 3;

Fig. 5 is a section on the line 5-5 of Fig. 3; l

Fig. 6 is a perspective of a section of the base cap;

Fig. 7 is an enlarged detailed view in elevation, partly in section. of the adapter4 shown in Fig. 3; 55

Fig. 8 is an enlarged detailed view of the retaining nut and spacing plug or sleeve.

Referring to the drawings by numerals of reference:

I provide a bomb body 10, ta ered toward its base or tail end to provi e a portion 11 over which the forward end of the base ca may slip.

he base cap is of substantially conical formation, though the walls of the cone may be slightly curved longitudinally as shown most clearly in Fig. l. The base cap is preferably made up of sections 12, herein shown as four 'iin number, the longitudinal edges of each section bent outwardly to form flanges 13.

It will be noted that the depth of these ianges is such that the `sections may be stamped out with the longitudinal curva.- ture mentioned without seriously straining or buckling the material of the flanges.

Between the anges of adjacent sections 12 the inner edges of the stabilizers or fins 14 are placed and the ianges bound against the stabilizers in any suitable manner. As herein shown, the flanges and stabilizers are provided with alining apertures through which rivets 15 'are passed or the same may be secured by spot welding or by a combination of riveting and spot welding. This gives the stabilizers a very rigid connection and braces the base of the stabilizer in an effective manner so that distortion thereof is unlikely.

To further secure the stabilizers against exure or distortion, braces 16 may be employed which extend between adjoining stabilizers to which theyare conveniently connected by means of riveting.

In order that the tin assembly may be held properly assembled on the body, I may ,provide a closure plug 17 which is threaded into or otherwise connected in the aperture formed in the base of the body 10, in which closure plug is threaded an' adapter 18 100 formed with a rearwardly extending tubular portion 19 convenient-ly threaded interiorly to receive the threaded end of a. plugu20 formed with an enlarged head 21 w 'ch seats upon the periphery of the rear end of the base cap and holds the same firmly in v place on the bomb body.-

each formed with flanges 13 as heretofore described and between these iianges the stabilizers or ns 14 are bound. The stabilizers or fins 14 in this instance, extending for a considerable distance to the rear of the base cap and the adjacent edges of such extending portions are conveniently bound together by angle strips 23 which may be riveted or otherwise connected in place as indicated most clearly in Figs. 3 and 5.

Braces 16 are provided for bracing the outer edges of these vanes similar to those hereinbei'ore described. An opening 24. may be provided in the fins to accommodate a wind wheel 25 through which the fuse is armed and also to permit assembling of the parts.

The tin assembly in this instance is assembled on the body as follows:

An adapter 18 is threaded into the base of the body and is formed with a rearwardly extending portion 19 into which is threaded a tube 26 which tube acts 'as a housing for the fuse mechanism and as a coupler to hold the iin assembly to the body. The outer end of this tube is threaded ex. teriorly to receive a nut 21 which seats upon the rear end of the base' ca and so binds the fin assembly in place. tubular plug 27 may be forced into the rear end of the tube 26 to properly center and holdA the fuse casing.

I claim:

1. A base cap and'stabilizer eonstruction for bombs, including a bomb body formed with a reduced rea/1` end, a base cap adapted to embrace the rear end, said cap comprisin sections bent outwardly along their longitudinal edges to form fian'ges,".ins secured between thefianges, a closure` element secured in the rear end .ofl the body and formed with a rearwardly extending portion and a plug connected to said rearwardly extending portion, said plug formed with an enlargedhead adapted to seat on the rear end of the cap to bind the cap in place upon the body.

2. A bomb, including a body formed with va reduced rear end, a base cap embracing the reduced rear end, said cap constructed of sections having flanged longitudinal edges, stabilizers secured between the flanges, a closure element secured in the rear end of the body, and a plug connected to said closure element and seated on the rear end of the cap to bind the cap in .place upon the body.

3. A bomb, including a body, a cap adapted toembrace the rear end of the body, stabilizers carried by the cap, a closure for the rear end of the body, and a plug connected to the closure and adapted to seat upon the rear end of the cap to bind the cap in place upon the body.

4. A bomb, including a body, a cap adapted to embrace the rear end of the body, stabilizers secured vto the cap, a tubular member connected to the body, means carried by the tubular member and engaging the cap to hold the cap assembled with the body, a fuse housedlwithin the tubular member and a closure for the rear end of the tubular member said closure centering the fuse within the member.
